Abstract

Dihydroxy-based polar organic cages (DIHO-cages) are reported to selectively separate toluene with 99.5% purity from an equimolar toluene/pyridine mixture, resulting in subsequent superior purification of pyridine. The efficient separation and purification, enhanced by strong and multiple host/guest C-H⋯O interactions between the cage and toluene, showcases DIHO-cages as a suitable candidate for the remarkable separation of such azeotropes on an industrial scale.

摘要

据报道，基于二羟基的极性有机笼（DIHO-笼）能从等摩尔的甲苯/吡啶混合物中选择性地分离出纯度为99.5%的甲苯，从而实现吡啶的高效提纯。笼与甲苯之间强烈且多样的主客体C-H⋯O相互作用增强了这种高效分离和提纯效果，表明DIHO-笼是工业规模下显著分离此类共沸物的合适候选材料。
